FRAME FOR STEAM AND OTHER POWER ENGINES.

SPECIFICATION forming art of Letters Patent No. 259,053, dated June 6, 1882.,

Application filed January 3, 1882. (No model.)

To all whom it may concern:

Be it known that I, LoUIs SOHUTTE, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain Improvements in Frames for Steam and other Power Engines, of which the following is a specification.

My invention relates particularly to what are most commonly known in the art as backaction engines, in which the crank-shaft is beyond the rear end of the cylinder, while connection therefrom to the piston-rod is made by a double-crank shaft, two connecting-rods, and

a cross-head attached to the piston-rod in front of the cylinder.

I am aware that engines of the above description have been made in various forms, and I make no broad claim thereto. Y

My invention consists in an improved construction of the main frame, the same consistin g essentially of a broadened base portion, a central standard curving upward therefrom, and constructed toward its upper end to sustain the cylinder, shaft-supporting webs or arms extending upward from the base and outward from the standard on one side, and cross-head guides extending in the opposite direction, as hereinafter explained in detail.

In the accompanying drawings, Figure 1 represents a side elevation of my improved engine; Fig. 2, a top plan View of the same.

Referring to the drawings, it will be seen that the base of the entire structure is-a strong symmetrical central frame, A, having a broad base of an elongated rectangular form and diminishing in width toward the top, where it receives and sustains the horizontal cylinder E. The heightof the main frame is deter mined by the size of the fly-wheel of the engine, as I preferably extend the base-frame under the wheel to a point beneath or beyond its axis. Its side plates preferably terminate in the circular upper ends, adapted to receive heads J are extended beyond the front side of the main frame A, being preferably cast upon the forward cylinder-head, as represented in the drawings.

The frame constructed as above is at once light and cheap in construction, but at the same time affords a firm and rigid support to the working parts, enabling the engine to ru without perceptible jar or vibration.

The engine may be constructed with an autom atic cut-ofi' valve or a simple slide-valve.

While my method of constructing the frame and its connection is designed more'particularly for steam-engines, itis manifest that the same may be applied to gas, air, and other power engines.

Having thus described my invention, what I claim is l l. The improved frame for a back-action engine, consisting of a flat elongated base, the central portion curving upward from the two ends of the base and gradually contracted toward its top, a horizontal cylinder mounted upon the upper end of said central portion, the cross-head guides extending from one end of the same, and the shaft-supporting arms extending from the opposite end of the same and supported directly from the base portion, as shown.

2. The engine-frameconsisting of the broadened base portion, the central portion or standard, curving upward from the ends of the base and terminating above the center of the base in a contracted portion, and the shaft-supporting arms or webs B, extending upward from the base and outward from the standard, as described and shown.

3. The frame A, constructed with a broad base and contracted thence upward to the center, in combination with the cylinder and its circular supporting-checks bolted to the top of the frame, substantially as shown and described.

4. In an engine frame, the flat rectangular base portion, the standard, curving inward and upward from the two ends of said base and adapted to receive the cylinder at their upper ends, and the main shaft-supports B, extending upward and o'utward,as shown, with bearings substantially over one end of the base.
